IMPORTANT UPDATE (08/20/26): CCNY Email Migration to CUNY
Email Content: We have completed copying email content for all users who were listed as Active in CUNYfirst. Most users should now have their email content available in their new CUNY mailbox.
Retirees: Retirees have also been migrated, with the exception of retirees who have not updated their CUNYfirst password. If you are a retiree who has not yet updated your CUNYfirst password, please update your password and then contact the OIT Service Desk to complete your email migration.
Departmental Service Accounts & Shared Calendars: Most departmental service accounts and shared calendars have been migrated and their content copied. If you previously had access to a departmental service account, please make sure you add the account to your Outlook profile. In Outlook, go to Settings → Accounts → Shared with Me → Select Add. For shared calendars, open Calendar in Outlook, select Add calendar → Add from directory → Search and select Add.
Distribution Lists: Migration of distribution lists is still in progress. Many lists are functioning, but we have received reports that some lists are not yet working properly. We are working with CUNY to resolve these issues.
Hardware Tokens: If you use a hardware token for authentication and have not yet registered it with CUNY, please contact the OIT Service Desk for assistance. Please have your hardware token handy.
Microsoft Outlook App: We are aware of an issue with some versions of Outlook that may retain the old CCNY mailbox information. When attempting to add the new CUNY mailbox, Outlook may indicate that the account already exists. If you experience this issue, follow the troubleshooting instructions. or contact the OIT Service Desk for assistance. In the meantime, we recommend using Outlook on the web to access your email.
We appreciate your continued patience as we work with CUNY to resolve the remaining issues.
Effective Wednesday, August 12, 2026, CCNY began migrating its email system from CCNY’s Outlook to CUNY’s Microsoft 365 platform.
Going forward, users must reconfigure each of their devices’ email settings to access CCNY email, using your CUNY username ( first.last##@login.cuny.edu ), password, and MFA.
During this transition, the most convenient way to access email is via the Microsoft Outlook web interface:
https://outlook.office.com
Users may briefly be unable to fully access their email mailboxes and calendar events as part of the synchronization process.
Instructions and more information are available below. If you require direct assistance, the IT Service Desk is available from Monday-Thursday 8AM to 5PM.

Setting Up Microsoft 365 MFA (Microsoft Applications)
CUNY and CCNY have implemented Multi-Factor Authentication (MFA) for CUNY Login, CUNY Office 365, and CCNY applications. This added layer of security helps protect both your data and CUNY’s and CCNY’s data from potential cyberattacks.
While the experience will feel similar to the existing CCNY MFA, users must complete this setup specifically for their new email account: @cuny.edu. Having MFA for CCNY does not automatically cover this new mailbox.

How do I configure my device, to add new mailbox?
The following instructions will assist you
Will all our calendar appointments be transferred?
Yes, calendar appointments will be transferred as well.
Will shared/departmental email accounts be transferred and remain available?
Yes, shared or departmental email accounts are being transferred to Microsoft 365 with the corresponding permissions - you will not need to do anything.

The size limit for attachments is 35 MB.

Why do I need to set up Microsoft MFA?
Microsoft multi-factor authentication (MFA) provides additional security and privacy when using CUNY Login credentials to access Microsoft 365 applications. Although similar to the CUNY Login MFA used when logging into other CUNY and college applications like CUNYfirst and Brightspace, Microsoft MFA is only used when accessing your new CUNY email account and Microsoft 365 applications.
How do I set up Microsoft MFA?
For information on setting up your Microsoft multi-factor authentication (MFA), see CUNY Microsoft Login MFA Set Up.
What email information will CUNY copy to my new CUNY email account?
- Emails: All email content, including folder structure and attachments.
- Calendars: Events, attendees, and recurrence patterns.
- Contacts: User contact information.
- Email Rules: Mail redirects, blocking rules, and other mailbox rules.
- Auto-reply Settings: Out-of-office replies and other automatic response configurations.
- Time Zones: Preserves the correct time zone settings for the mailbox.
What is Not Copied (Limitations):
- Encrypted Emails: Cannot be detected and are migrated unreadable.
- Folder Permissions: Permissions for folders are not preserved during the migration.
- Reference Attachments: Links to documents on OneDrive (like OneDrive for Business) are not preserved.
- Scheduled Emails: Future-scheduled emails are copied as drafts, not with their scheduled send time.
If you have multiple college affiliations, it may be helpful to set up a separate folder for each college email address and establish rules in your new CUNY email account to automatically move auto-forwarded messages into the corresponding college folder. See Managing Multiple Email Addresses on this SharePoint site and Set up rules in Outlook on the Microsoft website for more information.
